Note that there are only two integrated circuits used in the audio generator!

Function Generator

Thomas Henry just doesn’t give up on an IC. I’d say your best bet for the is BGMicro a very cool little outfit that supplies all kinds of spiffy stuff for this obsession of ours.

This is not a difficult project to build. The above circuit will offer you a alternative by helping you to build a Function generator by your own. Leave a Reply Cancel reply Your email address will not be published.

Additionally In my version of device i added the input mode for the meter, which can be selected on the range switch, and the output connector can be used to measure external signals. This circuit is capable of giving three output signals such as Sine, square and triangle which forms the basic types of signals. Gdnerator back and forth between these to pots to arrive at a solid 20 Hz to 20 KHz range.

An oscilloscope is pretty much required for setting symmetry generaror the waveforms. Amplitude and DC offset adjustment Waveforms obtained in this way still need to be fed to the operational amplifier that will allow setting of the amplitude and DC offset.


Function Generator Circuit using ICL Function Generators are an essential equipment for electronic hobbyist and experimenters to feed input signal with ease other than generating them by their own. R1, Symmetry Trim sets the symmetry of the waveforms above Hz or so.

Shown generator board allows connection of such a meter, giving him power supply and signal to probe. Notify of all new follow-up comments Notify of new replies to all my comments.

An genfrator attenuator is provided to scale this voltage to the desired range of control.

This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. Turn R25 and R26 to their lowest settings.

As it turns out, what the needed was a good change of diet. As you peruse the schematic, you’ll find the typical elegant economy of of a very effective design that is Thomas’ virtual trademark. It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, Ick8038 Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.

Even though the marks on Thomas’ panel design are only approximations to help find the ballpark, a better quality coarse pot will put you closer to those marks. Voltage transformer should have a 2x14V minimum to allow the proper operation of and stabilizers.


That allows you to put it on your bench top and use it to test your audio circuitry. Though it does use linear control voltage, it’s doubtful it would track a linear voltage produced by, say, a keyboard of a Korg MS, which produces a linear control voltage, but it would gfnerator great for sweeping and modulation effects.

ICL8038 Function Generator

Audio oscillator circuit Simple function generator circuit Digital thermometer circuit Capacitance meter using LM Frequency to voltage converter using LM R22 is the Low Frequency Symmetry Trim – it is used to ensure the waveforms hold their symmetry below Hz. Frank Donald is an Electronics and Communication Engineer who loves building stuff in his free generstor.

Shown in the schematic LM 1. The frequency control set consists of a coarse and fine tune arrangement – the coarse control obviously will move the frequency in greater increments, and the fine control allows one to set the frequency exactly at the desired point. How to deal with it? That alone catapaulted the from mediocrity to true A Number One function generator-hood. Frank Donald June 10, 1 Comment. If you’d like to etch a PCB for your audio generator, the PCB layout and parts genedator document are available for download below.

It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors. It features sine, triangle and square wave outputs.
